But it doesn't check if the adapter is one of those or if a VGA16 mode is used. This means that the driver will be probed even if a VESA BIOS Extensions (VBE) or Graphics Output Protocol (GOP) interface is used. This issue has been present for a long time but it was only exposed by commit d391c5827107 ("drivers/firmware: move x86 Generic System Framebuffers support") since the platform device registration to match the {vesa,efi}fb drivers is done later as a consequence of that change. All non-x86 architectures though treat orig_video_isVGA as a boolean so only do the supported video mode check for x86 and not for other arches.
